Inconel 625 round bars are widely recognized for their exceptional strength, resistance to oxidation, and ability to withstand extreme temperatures. This high-performance alloy is used in various industries, from aerospace to chemical processing, and is especially known for its ability to resist corrosion, making it a preferred choice for many high-stress applications. In this blog, we will explore everything you need to know about Inconel 625 round bars, including their features, applications, and benefits.
What is Inconel 625?
Inconel 625 is a nickel-chromium alloy with molybdenum, niobium, and iron added to it. All these elements combined give the material good resistance to oxidation, carburization, and general corrosion. The presence of niobium gives it high strength and toughness, and molybdenum enhances its resistance to pitting and crevice corrosion.
Inconel 625 round bars are manufactured by hot rolling this alloy into cylindrical bars that can be further used in forms such as rods, tubes, or custom-cut pieces. The bars are made to be strong and flexible for high-temperature and high-pressure applications.
